That is a good question. The F21's were tested by TRA but they have been expired and the G55's, well they are not on an approved list. I will have to consult more or at least send the experts over here to answer your question. But in my understanding since these motors are not certified or in the case of the F21's, have expired, you can not use them at a CAR/ACF launches and are not valid for record attempts.

Any TRA or NAR certified motors are acceptable at a CAR/ACF launch. As far as expired certifications, recertification is for newly produced motors. It has been generally acceptable to use motors which were from a certified production run. There is an exception which applies to ALL motors, Should there be any evidence of improper storage such as too wet, too cold or too hot, these motors can not be used. Any such determination needs to be assessed by the flier and is subject to a determination by the RSO.

This also raises the question of purchasing motors from other fliers or questionable storage in the past. Basically, If you are not sure, it is likely better to avoid such motors or things might not go your way.

Just to clarify, these motors can then be used at a CAR-ACF launch based on the qualifications you’ve stated above. Does this then permit them to be used for altitude record attempts? Will these motors be recognized officially for altitude record attempts even though they’re now uncertified?

Generally speaking, the TRA and the NAR have programs based on US law and requirements. We happen to be in a different country. We certainly do look to them when we review things but in the end we operate under Canadian requirements.

With regards to motor usage, our requirements come from a combination of:

1) ERD requirements mainly focused on the National Explosives Act.

2) The CAR/ACF motor testing requirements.

3) TC requirements and expectations.

3) The CAR/ACF also needs to weigh risks to protect and preserve our insurance and the privilege to maintain a program.

4) Through the motor certification process, the performance of motor is confirmed thereby by ensuring that is conforme to the above AS WELL AS confirming that the impulse conforms to the reqirements laid out in the certification process. No valid or legal assurance exists with uncertified motors.
